Messenger

In her article "Shooting the messenger: Why Canadians don't blow the whistle on wrongdoing" Suanne Kelman aims to unravel the Canadian stigma regarding whistleblowers. Last year, when Wikileaks declassified a large quantity of corrupt government documents, the general canadian's reaction was not one of solidarity, but rather of condemnation. Kelman believes that, "somewhere in the Canadian psyche there seems to be a rooted belief that whistleblowing is not nice"(200). This explains why the…

Module #11 Chapter 21 Books cited: Becker’s world of the cell: J. Hardin, G. Bertoni, and L. Kleinsmith: 8th edition; pgs. 645-646 & 657–659. Question #1 from D2L: What is the central dogma of molecular biology? The central dogma is the explanation of how genetic information flows as it is passed from DNA to RNA to protein. DNA replicates and converts the information it carries into RNA, this process is called transcription. During transcription the information is passed through nucleic…

Jennifer is a blithe and free little woman who has been notable in a bakeshop in Flushing for a quarter of a year. She stands restlessly among customers in a crevice between two small shops. Once in a while she trudges up and down Main Street seeking attention, even something as little as a smile from someone else. She sometimes makes eerie sounds, and ends up scaring people off, making it difficult for her to get her point across. As people walk away from her, she begins to wail her arms up in…

it can't, so what does it do then? The answer to that, is that DNA makes a copy of one of its helixs to get out of the nucleus. The process of DNA making a copy of itself is called transcription. The copy of the DNA is called mRNA and that is the messenger type of RNA. The DNA makes a copy of itself called mRNA, then gets out of the nucleus and leaves to attach itself onto a ribosome. The process of the mRNA attaching itself to the ribosome is called translation. The ribosome acts as a "Zipper"…

In modern molecular biology and genetics, the genome is the genetic material of an organism. It consists of DNA (or RNA in RNA viruses). The genome includes both the genes and the non-coding sequences of the DNA/RNA. Understanding Human Genetic Variation Genetics is the scientific study of inherited variation. Human genetics, then, is the scientific study of inherited human variation. We study genetic material due to following reasons; 1. One reason is simply an interest in better understanding…

Prokaryote DNA replication is a semi conservative, bidirectional, template driven process. The phrase ‘semi-conservative’ refers to the fact that the newly synthesised double stranded DNA is made up of one parental (existing) strand, and one newly synthesised strand. The parental duplex is not ‘conserved’ as an entity. This was proved by the Meselson-Stahl experiment by replicating E.Coli in different mediums of of different Nitrogen isotopes. The results consisted of half of normal weight and…

Each gene has instructions to make or build a protein. In protein coding the sequence is always in groups of three nucleotides. These groups of three are called codons. Every codon has one amino acid in a protein. All proteins need to start with the ATG codon. Most biological activities are carried out by proteins. In order to have the DNA sequence that reads ATG-ACT-CAT-GAG-TGA to be translated into the RNA to build a protein there has to be proteins that are not the same to be able to…

proteins could never be made (News-Medical). Transcription is the process of making an RNA copy of gene sequences. This particular copy leaves the cell nucleus and enters the cytoplasm. Translation is the process of translating the sequence of a messenger RNA (mRNA) molecule to amino acids during protein synthesis. In the cell cytoplasm the ribosome reads the sequence of the mRNA in groups made up of three bases to assemble the protein (NIH). DNA, RNA, Transcription, and Translation are all…

Differential alternative splicing human tissue network analysis of GUK1 Result Figure 4.12: Visualisation of alternative splicing gene GUK1 in human tissues. Differential alternative splicing genes between two different tissues comparison were shown on a different visualisation platform and tools in comparison with network analysis. (A) rMATS analysis. Histogram shows inclusion level ψ, per sample for each tissue comparisons. In this case, only exon 3 found as statistically alternative…
